摘要
目的 探讨常规体表静息心电图 Tv1( Tv2 ) >Tv5( Tv6 )在冠心病诊断中的价值。方法 1 1 0例住院行冠脉造影的患者 ,按造影结果分为冠心病组和非冠心病组 ,两组均多次记录常规十二导心电图 ,比较 Tv1( Tv2 ) >Tv5( Tv6 )综合征在两组间检出率的差异 ,并与心电图 ST段压低指标相比 ,分析 Tv1( Tv2 ) >Tv5( Tv6 )综合征诊断冠心病的价值。结果 Tv1( Tv2 ) >Tv5( Tv6 )综合征的检出率在冠心病组和非冠心病组有显著差异。 Tv1( Tv2 ) >Tv5( Tv6 )诊断冠心病的敏感度为 70 .3 %、特异度为 66.6% ,与 ST段压低相比敏感性较高 ,但后者特异度高于 Tv1( Tv2 ) >Tv5( Tv6 )。结论 Tv1( Tv2 ) >Tv5( Tv6 )综合征对诊断冠心病有一定价值 ,但特异性不高 。
Objective To investigate the possible velue of the Tv 1(Tv 2)>Tv 5(Tv 6) syndrome in the diagnosis of coronary artery disease(CAD).Methods Electroncardiogram was perfomed in 110 patients,including 74 cases of CAD and 36 cases of non-CAD cofirmed by coronary angiography.The Tv 1(Tv 2)>Tv 5(Tv 6) syndromed and ST segment depression as the diagnosis standard of CAD were analysed on the basis of the coronary angiographic findings.Results The incidence of the Tv 1(Tv 2)>Tv 5(Tv 6) syndrome in ECG was significantly different between CAD group and non-CAD group.The sensitivity of Tv 1(Tv 2)>Tv 5(Tv 6) syndrome for detecting CAD was 70.3% and the specificity was 66.6%.The Tv 1(Tv 2)>Tv 5(Tv 6)syndrome was more sensitive than ST segment depression for detecting CAD,but ST segment depression for detecting CAD was more specific than Tv 1(Tv 2)>Tv 5(Tv 6)syndrome.Conclusion When Tv 1(Tv 2)>Tv 5(Tv 6)syndrome was combined with other indexes of ECG and clinical data,it would be a useful criterion for the diagnosis of CAD.
